I 17 Claims.

This invention relates to machinesuseful in setting, drying or otherwise treating textile products such as hosiery or the like in preparation for marketing. More particularly, it is concerned with machines generally of the type disclosed in U. S. Patents Nos. 2,243,997 and 2,321,452,

7 granted us on June 3, 1941, and June 8,-1 9f13',1r:e-

spectively, wherein the articles are placed on supports which are shiftable along guideways and movable into a chamber wherein a suitable fluent .treating medium is circulated to permanentize.

the shape of thearticles. *In eachof the patented structures a section of the guidewayis attached to the door of the compartment and must be-displaced laterally to'introduce the article supports into and remove them from the treating chamber. This door displacing consumes considerable time and detracts to a corresponding degree from the efficiency of the -machines from the standpoint of their output capacity.

One of the aims of our present invention is to overcome the drawback -just referred to. This objective is realized, as hereinaftermore fully disclosed, through provision of' 'an improved treating apparatus having a treating chamber with doors at opposite ends thereof, a guidjeway which extends through the treating chamber at the bottom, and'means whereby one support .is passed in to the chamber concurrently with'the removal of another. 1 .In'connection with a textile treating apparatus having the foregoing attributes, it is a] further object of our inventionto provide mechanism whereby the doors 'of the treating chamber are automatically opened and, closed by the 'form supports as the latter are moved along the guideway. 1

Another aim of our'in vention is to attain further increased'output from and greater oper ative economy in a machine of the character referred to which desideratum is made possible Fig. 2 is a broken out view showing themachine rigidly mounted a housing 2. housing 2 is constructed with walls of sheet ma-- terial whereof the component panels are united partly in side elevation and partly in longitudinal section. Y I V r Fig. 3 shows the top plan of the'machine." Figs. 4.and 5 are transverse sectional views taken as indicated respectively by the angled arrows IV-IV and V-V in Figs. 2 and 3.

Fig. 6 is a horizontal sectional view taken'as indicated by the angled arrows VI-VI in Figs. 2 and 4. I a Fig. 7 is'a broken out fragmentary view in hori zontal section taken as indicated by the angled arrows VII-VIIin Fig. 2.

Figs. 24-26 are views like Fig. 23 showing how the control system functions under different con ditions of operation.

With reference first more particularly to Figs.

1-6 of these illustrations. it will be seen that our improved textile treating machine comprises a transversely-arranged base frame .I whereon is As shown, this at their meeting edges by angle strips 3. Laterally spaced partitions 4 and 5'set apart within the housing, a central compartment 6 between two 3 flanking treating chambers 'l and. 8. The partitions 4 and 5 terminate short of the roof 9 of the housing, see Fig. 5, for communication of the treating chambers l and 8 at their tops with the pin 68 secured between said lugs.

'in Figs. 16-19, th pivot element l0 connecting housing walls, are lined with insulation, and which are hinged as at l9,.2fl and 2!, 22 to the framing of the housing at the opposite side edges of the door openings.

Disposed in the central chamber 6 is a blower 25 with its discharge duct 26 extended upwardly and fitted into an opening in a diaphragmll bridged between the partitions 4 and 5. Surmounting the discharge outlet .of the blower above diaphragm 27 is an open shroud 28 which surrounds a transversely-positioned heating coil 29 supplied with steam by way of piping 30 under control of the pressure reducing valve shown at 3! in Fig. 1. During the operation. of the machine, air drawninto thesideof the blower 25 is discharged through the outl et 26 of theclatter and caused to divide equally into two separate streams by curved bafiies 32 and .33 in the top corners of the housing, the air being thereby diffused and at the same time directed to pass downwardly in the treating chambers l and 8. Similar curved bafiies Hand 35 in the lower portions of the chambers serve to retard the two air streams before they pass through the screened windowslfl and ii into compartment 5 for recirculation by the blower 25. In traversing the coil 29, the air is of course heated before division of the fiowas above explained. The blower 25 is driven, through a belt connection 3B,,from an :electric motor 39 supported within the base frame I.

Arranged longitudinally ofthe machine to equal distances beyond the housing 2 centrally of and below the treatingchambers 1,5 are guideways 49 and 4i which are identical inconstruction. As instanced' in Eigs. 3-51.15, "ifi each of the guideways 40, 41' comprises a pair, of laterally-spaced track rails 42 whichare supported at opposite ends of the guideways .by stool frames, and which at intermediate, points, are supported by crosswise arranged U-shaped cast ings 44.. The parts just described are rigidl'y connected together by longitudinally-extending tie bars 45. Extending aroundithe ends of the guide- ,ways 45, 4| and throughout. the greater portions of their lengths at opposite sides thereof are "guards 48; and attached to the guideways atthe inner sides are trays 4? for holding piles'of the textile articles which are to be treated.

Movable on the rails 42 of the guideways and 4i are supports 50, 5iv and 52, 59 respectively.

These supports 50 and 5i are identical in con.-

struction but oppositely arranged on the tracks, each being in the form. of a lazytong, seeFigs.

'16-22, comprising a plurality of crossed' links 55,

pose later on explained, with a dagger-like cam projection 59 having a lateral projection 59 with an upright stud 5i. Upstanding from alternate crossed links'56 are pairs or lugs 62and 53 :which 4 are laterally spaced for reception between them of flat upright forms 65 over which the textile articles are drawn and held to shape during treatment. For convenience of exemplification herein, the forms 65 are shown as being profiled for ladies hosiery. Each form 65 has notches .in its :bottom'edge to engage downwardly over pins 59 extending crosswise between the lugs 52, 63, of the corresponding link 56, and is held in place by a wedge lever 61 fulcrumed about a pivot As best seen the endmost pair ofcrossed links 55, 56 has a cylindric stop head Tl with a circumferential vflange 12 to engage upwardly against the bottom faces of the rails 42, a diametrically-reduced cylindric portion 73 to engage between the rails, and a rounded l4 shank to serve as the connecting pivot for said links. The pivot element (9 is held in assembly by a pin 15 passed through a diametral aperture in the shank portion 14 of said element and through registering apertures in the link. An arcuate keeper element E5 of flat spring metal engaged through a. transverse aperture in the top protruding end of the shank of pivot element Ill holds the link 56 assembled with its mate 57. The pivoting elements Tl (Fig. 20) iorsomeof the other pairsof links 56, 57,

except for the lack of a bottom head, are like Themeans provided for progressing the form sup-ports associated with each guideway, includes .an elongate subcarriage 85, see Figs. '7 and 8, consisting'offa bar 86 which is arranged for travel on a pair of laterally-spaced longitudinal rails 81 supported by and secured to the main frame .I, the stool frames, and the castings 44 at a level below the rails 42. Secured centrally of the bottom'of the bar 86 is a co-extensive toothed rack 88 which fits into the interval between the rails. 81 and whereof the teeth are in mesh with a spur gear 89 afiixed to, a transverse shaft I94. In the region of the spur gear 89, the carriage i prevented from rising from the rails 81 by an overlapping hold down plate 9! rigidly sustained by the brackets 92. Affixed to and extending from the carriag'e'bar 86 adjacent opposite ends thereof, are lateral brackets 93 and '94 whereto are secured in turn, arm extensions 95 and 95 with rollers 91 and 98 to run on a supplemental track rail 99 which is supported by the frame members in the same manner as the rails 87 in parallel relation to the latter. Upstanding from the extensions 95 and 96 are coupling studs I05 and Hill which engage upwardly into socket holes in the central .pivot elements E9 of. the form supports as best seen in Figs. 16 and 17.

' The machine-is powered by "aseparate reversible electric motor I02 (see Figs. 2, 4, 5 and 9) with an associated speed reducer N13 to the output shaft I04 of which latter is afiixed the rack gear 89. Through'a pair of spur pinions'l05, 106, rotary motion is" communicated to a transverse shaft lll'i having a spur wheel 19 thereon for driving the carriage rack 88 at the other side .of the machine.

For description of the mechanism. provided for oi the machine. Accordingly, by operation of -,the

motor I02, thecarriages'on the respective guide- .ways are propelled in opposite directions .at each actuation. Forthe' purpose of automatically stopping-the motor .I02 when the carriages reach thelimitsof travel in opposite directions, we have provided on one of the guideways, apaiizof'li-mit switches H and ,I II (Fig. '1) which arefixedly secured to "such guideway. As shown, the switches H0 and III are 50 located that their actuating arms H2 and H3 respectively extend into the path of cam pieces H4 and H5 at opposite ends of the carriage. Centrally of the front end of the housing 2 is a switch with push buttons H6 and H1 for startingand stopping the fan motor 39, and a switch with push buttons .I I8 and I I9 respectivelyfor starting the carriage propelling motor I02 and for emergency control automatically opening and closing the doors of ',the respective treating chambers 11anda8, refer ence will now be had to Figs. 6, -15 and 18 of the drawings. Extending crosswise of each treating chamber at the top is a shaft I26 which, at

opposite ends, isjournalled in bearings I 2| and ,I22: respectively on a side wall and on a partition of the housing2. Pinned to the shaft I are levers I23 and I24 whereof the oppositely-extending arms areyc'onnected respectively, by

means of adjustable link rods I25, I26 and I21,

' I28, to lug brackets I29 secured to the doors I5,

I6 and I1, I8 at opposite ends of the compartment adjacent swinging edges of said doors, One arm of lever I24 is somewhat longer than the other arm, and pivot'ally connected by one of its corners to the end of said longer arm is a triangular element I30 which is made to open configuration so as to clear shaft I20. The element [30 is subject to a toggle spring I3I whereof one end is hooked to a pin I32 centrally of the side opposite the pivot corner of said element, and whereof the other end is secured to a fixed anchorage. I39 on the partition. Incident to advance of one oi the formsupportsjl along its guideway from within the compartment in the direction of the arrow in Fig. 12 for example, the -dagger.59 of said support. will engage the door I1 to start opening it. Through motion com- .municated by thelink rod I21 to shaft I20, the other doors I5, I1 and I6 of the group will be opened at the same time. Eventually, when lever 7 I24 has been moved beyondverti'cal dead center relation in respect toshaft I2 0, the toggle spring I3I will take over and cause the doors to be swung suddenly to full open position as in Fig. 11, such position. ;being determined by engagement of lever I24 with a fixedadjustable stop I35. As theother form support 56' enters-the compartment (which in the meantime has been vacated by the form support 5I) as shown in Figs. '14 and15, the upstanding stud 6I on the dagger 59 thereof will eventually engage a lateral projjection I36 adjacent the'hinged edge of door I5 to start closing it. This movement is communi- 'ca ted through the linkage to shaft I29 which will now be oppositely turned, and, upon movement of way to closed position.

In addition to the switches H0, III, H6, H1, H8, H9 alreadyreferred to, other'instrumentali- 'ties utilized in controlling the functioning of the machine include, as shown in Figs. 23-26, multi- .forms85 on said supports.

ple contact relays I40, I4I, I42v and I43, the spe cific functions of which ,will be presently described. I

The current for operatingthe machine is sup- Y plied from athree phase line of which'the mains are designated I45, I46 and I41. .Inorder to facilitate reading of the diagrams of Figs. 23-26,

and thelive circuits in heavy lines.

' Operation Assuming the form supports to be positioned as shown in Fig. 3, i. e., with thesupports50-and 53 extended at the extreme left and right hand ends of guideways 40 and 41 and the supports 5I and 52 collapsed within the chambers 1 and 8. With thesupports so'positioned, attendants respectivelystationed at A and B between the guideways 40 and M apply the stockings to the The Start button the dead circuits are indicated in light lines,

H6 (Fig; 24), is then pressed to establish current mains I45, I46 and I41 to the tap wires I58, I59

'the lever'I24 past center in the reverse direction, the toggle spring I3I will again take over and cause all of the doors to be swungthe rest of the 70 and I60 of fan motor 39 by way of conductors I6I, I62 and I63, and contact bridges I64, I65

and I66 of relay I40. The fan motor 39 being now in operation, the start button I I8 is pressed, whereupon current flow will take place from conductor I6I, through conductors I61, I68 coil of relay I4I, conductors I69, I10 and HI, bridge plate I12 of limit switch III, andconductor I13 to conductor I63, likewise as shown in Fig. 24. The circuit just described is maintained upon release of switch I I8, by current by-passed across the contacts of the'latter through branch. conductor I14, bridge plate I15 of relay I4I,,and branch conductor I16.

results in current flow from conductor I6I byway of conductor I61, tap I54, coil of relay I42, conductor I11, plate I18, conductor I19, contact I93 of limit switch H0, and conductors I94 and I13, to conductor I63. As a consequence of the closing of'relay I42, current will be supplied to the.1eads-'I8I, I 82, I83 of carriage rack. drive motor I02 respectively byway of conductors I84, '-.I85 and I86, and contact-bridges I81, I88, I89 of said relay. Under drive of motor I02 in the'di- .rection of the arrow thereon in Fig. 24, the form 'supports50 and 5| will be progressed rightward on guideway 49 in Fig. 3, and the'supports 52 and 53 progressed leftward on guideway 4|." In-' cident to such travel, the form supportsj5| and 52 will be extended as they leave the treating chambers 1 and8, and the supports 50 and 53 will I be collapsed as they enter said chambers, this action taking place automatically'due to friction between the center pivots of the lazytongs with the track rails 42. Also incidently, the doors of the chambers 1 and 8' will be openedand'closed automatically in the manner already understood. As theform support carriages approach the opposite ends of guideways 40 and M, cam H5 will pass beyond the actuating arm'l I3 of limit switch I I I, with consequent retraction of contact bridge -I12- from the terminals of conductors ;I1I and I12, and interruptionof the current 'fl'owin the Closing of relay- I4I coil of relay [M which. will then open. Notwithfan motor 39 when the form support propelling carriages have reached the ends of their traverse. At the completion of this operative cycle with the parts positioned as in Fig. 25, the relay I43 will still be held closed through energization of its coil by current flow from conductor I55, contactbridge I56, relay I43, branch conductor I51, conductor [52, closed switch H1 and conductor I53, to main I41. Also at the completion of the cycle, the form supports 50 and 53 will be collapsed and within the chambers 1 and 8, and the supports 51 and 52 expanded and positioned respectively at the right and left hand distal ends of the guideways 4c and 4i. While the articles on form supports 53 and 53 are undergoing treatment in the chambers I and 8, the attendants stationed at A and B remove the previously treated articles from the forms on supports 5! and 52 and replace them with new ones in readiness for treatment during the next operative cycle of the machine, which is initiated by again pressing the Start" button H8. Due to setting of the limit switches III] and III as in Fig. 25

by the cams I I4 and I I5 during the first described cycle, the live circuits of the control system will now be as in Fig. 26, i. e., with the coil of relay I II energized and the latter closed by current flow through conductors I61, I58, I65, I10, contact bridge I95 of limit switch iiil, tap I96, and

conductors I13, I53. Relay I 33 will also be closed now by current flow through its coil by way of conductors I6I, I91, I93, contact bridge I99 of relay MI, conductors 2'85, Zill, contact bridge 282 of limit switch III, and conductors I13, I69, and

be held closed by current flow through conductor 204, contact bridge 2G3 and conductor 20L As with attendant opening of relays I and I4], as well as of relay I42 or I43 whichever of the latter two may be closed. at the time. If, after such stoppage, the Reset button H9 is pushed, the motor I02 will be reversed as in Fig. 26 and the form support carriages returned to the positions in which they are shown in Figs. 2 and 3.
